I had them on my 93 CC. Repair costs for the a 3 foot section on each side of the hull about $600. I would be screaming to the dealer and the factory on an '03 boat. It is my understanding that they are caused by pockets of trapped air inside the gelcoat. CC used AME500, which is supposed to be the best, and it still happened to me. If you find the right gelcoat person, you will never be able to see the repair. This is becoming common in many production boats. I just purchased a new '01 Tige 22i R, hoping that I don't have a similar problem. Understand, I was not dissapointed in with my CC. Things happen!

This is one thing that Correct Craft warranties under their 5-year promise... no matter whether you have a colored hull or not. I am sure any dealer would be willing to fix that on any new boat... because it shouldn't happen that fast.

blisters should not be in the gel coat. this is usually caused by either inferior materials, bad application or a combination of both.

from what i understand, if the epoxy resins aren't mixed correctly, if they start to set-up before the process is finished or whatever....imperfections can form and blisters can develop. due to batch processing, the hulls before and after may have the same problems.

do you keep it in the water?....don't hear about new tourny quality boats with blisters, its usually older cruisers docked all the time

Blisters are a major problem and not easily fixed! I also agree that they show up when water gets under the gel coat. I would be leary of buying a new boat that already showed them - definitely an application problem.

Blisters are caused by water absorbing into the fiberglass. Once the water gets in, the fibers expand causing the blister. Vinyl based as opposed to polyester based resins usually have better resistance to this if applied properly. Most good manufacturers will warranty against this, but check the fine print. Some warranties are void if the boat stays in the water for an extended period of time, sometimes as little as two weeks.

Thanks for all the info guys.. Sanger fixed my boat! Not only did they fix it, they waxed the whole thing for me! I really expected to have to fight for this to get fixed since it is excluded from warranty.. I didn't get a bit of resistance from Sanger. I was told that since it has been documented, if it happened again they'd fix it! I was surprised to see Sanger take full responsibility. 'It was obviously a manufacturer defect. There must have been contaminants somewhere in process of gel coating the boat' is what Sanger told me. What?! a manufacturer admitting they made a mistake?! Kudos! From what I understand, the boat making process is more of an art then a science and sometimes things happen. I'm pleased to know that Sanger is honest and is upfront enough to admit it was a mistake...This kind of service is what keeps people buying Sangers.. I can't even see where they worked on it.. they did a wonderful job! Thanks Brian, Scott and Sanger, you'll get a Christmas card from us this year.
